Can elevated BUN (blood urea nitrogen) and creatinine be the only signs of dehydration? In most of the cases, there are some other symptoms like dry mouth, fatigue, mild headache, dizziness, reduced appetite or chills. Then how does dehydration causes high BUN and creatinine level? How to deal with it?

Cause

Dehydration is a condition that occurs when the loss of body fluids, mostly water, exceeds the amount that is taken in. With dehydration, more water is moving out of our cells and bodies than what we take in through drinking.

When dehydration occurs, the blood volume in the kidney decrease, then many metabolic products of protein will accumulate in the body. Therefore, BUN and creatinine level elevates.

Other symptoms of dehydration

The signs and symptoms of dehydration range from minor to severe and include:

- Increased thirst

- Dry mouth and swollen tongue

- Weakness

- Dizziness

- Palpitations (feeling that the heart is jumping or pounding)

- Confusion

- Sluggishness fainting

- Fainting

- Inability to sweat

- Decreased urine output

Urine color may indicate dehydration. If urine is concentrated and deeply yellow or amber, you may be dehydrated.

When should you seek medical care

Call your doctor if the dehydrated person experiences any of the following:

- Increased or constant vomiting for more than a day

- Fever over 101

- Diarrhea for more than 2 days

- Weight loss

- Decreased urine production

- Confusion

- Weakness

Treatment

Drinking fluids is usually enough for mild dehydration. It is better to drink small amounts of fluid often, instead of trying to force large amounts of fluid at one time.

However, if the elevated BUN and creatinine level are caused by kidney disease, it is not enough by drinking water or taking medicines. Treatment should improve the kidney function. You can consult our online doctors. Our service is totally free.
